bunq API Access in Liechtenstein | Open Banking

Pulling your bunq data into your own tools no longer means wrestling with eIDAS certificates or bank-specific onboarding. With open-banking.io you link a bunq account held in Liechtenstein once and receive a clean, structured feed of balances and transactions through a single European open-banking API — the same endpoint that already reaches 2,600+ banks across the EU and UK.

bunq is a mobile-first neobank, so most people manage it entirely from an app. open-banking.io extends that reach programmatically, letting you mirror your bunq activity into spreadsheets, accounting software, dashboards, or any workflow you build yourself.

How to connect bunq

1. Create an account at open-banking.io and open the connection screen.
2. Pick bunq (Liechtenstein) from the supported-institution list.
3. Approve access in bunq's own secure login — your credentials go straight to the bank, never to us.
4. Choose the personal or business account you want to share.
5. Start receiving live data through the API immediately.

What data you get

• Accounts — identifiers and metadata for each linked bunq account
• Balances — current and available amounts, refreshed on demand
• Transactions — dated line items with counterparties, amounts, and references

Consent and coverage

bunq (Liechtenstein) supports both personal and business account types. A single authorisation stays valid for up to 180 days, after which a quick re-approval keeps the connection alive. bunq does not publish a BIC for this entity, so none is required to connect here.

Privacy by design

open-banking.io runs on a zero-knowledge model: we relay your authorised data without holding onto your banking secrets, and there are no eIDAS or QWAC certificates for you to buy, install, or renew. Authentication happens inside bunq's environment, keeping you in control of every consent.

Pricing

One flat subscription of roughly EUR 3 per month covers your bunq connection and every other bank in the network — no per-call fees, no tiers, no setup charges.

FAQ
